mol_generate_one_water()

Bmolecule * mol_generate_one_water	(	Bmolecule **	mollist,
		char *	watername,
		Vector3< double >	Ocoord
	)

Generates one water molecule at a given location.

Parameters

**mollist	molecule list.
*watername	molecule name.
Ocoord	oxygen coordinates.

Returns

Bmolecule* new water molecule.

molgroup_calc_water_rdf()

int molgroup_calc_water_rdf	(	Bmolgroup *	molgroup,
		double	interval,
		double	cutoff
	)

Calculates a radial distribution function for water molecules.

Parameters

*molgroup	molecule group.
interval	interval between bins.
cutoff	distance cutoff.

Returns

int 0.

molgroup_generate_random_water()

Bmolgroup * molgroup_generate_random_water

(

Vector3< double >

size

)

Generates a block of water with random placement.

The number of water molecules generated is calculated as:
    n = volume * 0.03346.

Parameters

size	size of block.

Returns

Bmolgroup* new molecule group.

molgroup_generate_regular_water()

Bmolgroup * molgroup_generate_regular_water	(	Vector3< double >	size,
		int	type
	)

Generates a block of water based on a regular lattice.

The number of water molecules generated is calculated as:
    n = volume * 0.03346.

Parameters

size	size of block.
type	type of lattice, 2=rectangular, 3=tetrahedral.

Returns

Bmolgroup* new molecule group.

water_angle_list()

Bangle * water_angle_list

(

Bmolgroup *

molgroup

)

Generates a bond angle list for a block of waters.

Parameters

*molgroup

molecule group.

Returns

Bangle* new bond angle list.

water_bond_list()

Bbond * water_bond_list

(

Bmolgroup *

molgroup

)

Generates a bond list for a block of waters.

Parameters

*molgroup

molecule group.

Returns

Bbond* new bond list.
